â¢ 7zX now behaves like Appleâs BOMArchiveHelper when expanding archives; existing files shouldnât be overwritten anymore.
â¢ The creation of archives has been improved; we fixed a bug which would prevent 7zX from creating any kind of segmented archives.
â¢ Self-Extracting archives also include the improvements we studied for the main 7zX application.
â¢ 7zX is now uses standard .plist files to store its preferences.
â¢ Compression options are now preserved across sessions.
â¢ Software update routines have been improved; 7zX now checks for updates at most once/day.
â¢ Some components have been removed or updated in order to improve performance and compatibility with Mac OS X 10.5.
â¢ Growl notification messages have been improved; 7zX now warns the user when a password is required to decrypt an archive.
â¢ Code optimizations.

7zX now creates temporary files in the same folder as the files it is processing rather than on the main hard disk. Also, huge portions of the code that constitutes 7zX have been rewritten, in order to increase software performance.

- Macintosh resource forks and Spotlight metadata are now stored in regular 7z archives using the AppleDouble standard rather than the proprietary Safe 7z format. An AppleDouble-compatible tool is still required in order to properly decompress these archives on a Mac.
- The reminders for donations which were present in the past releases of 7zX have been removed.
- Important portions of 7zX's source code have been rewritten, cleaned up and optimized.
- All components used by 7zX have been updated to the latest release.
